11/11. Rheumatic manifestations in the course of anaphylaxis caused by anisakis simplex. Human anisakidosis is a parasitic infection caused by the larvae of anisakis simplex. Classical clinical manifestations include epigastric pain, occlusion, diffuse abdominal pain, appendicitis, and anaphylactoid reactions. Arthralgias or arthritis have been infrequently reported. We present three patients with proven hypersensitivity to A. simplex together with rheumatologic complaints after ingestion of parasitized fishes. A. simplex must be considered in the differential diagnosis of arthralgias/ arthritis especially if associated with urticaria. ( info) |
